Petra Collins, Selena Gomez Collaborator and BFF, Now Has A Book of Selena Gomez-Approved Photographs

Still looking for a Christmas present for your artsy friend? Good news: Instagram-beloved photographer, and noted Selena Gomez collaborator Petra Collins has released a new book of her photographs, titled Petra Collins: Coming of Age. To celebrate the new tome, Collins gathered her non-Gomez BFFs for an intimate dinner party, hosted by Gucci, which drew out fellow Instragram-beloved cool kids Carlotta Kohl and Adwoa Aboah. This week, awards season officially kicked off at the Gotham Awards, where Oscar-hopefuls Nicole Kidman, James Franco, and Saoirse Ronan, among others, came together to celebrate this year's biggest movies. Meanwhile, British department store Harrod's touched down in New York, and Victoria Secret model Taylor Hill's younger siblings, Mackinley and Chase, stopped by a dinner for French brand ba&sh, proving they are certainly following in big sister's modeling footsteps. Here, take a look at the best party pictures of the week.
